i Specification of Letters Patent.

Patented May 22, 1906.

Applioetionlfiled July 9, 19Q4. Serial No. 215.856.

To all whom it may concern.-

Be it known that I, JOHN lNIoHoLAs Pn- TEnsEN, a citizen of the UnitedStates, and a oil-retaining, and in case the bearing is ap-' plied torolling-stock of railroads to lessen the friction of thewheel-fianges'against the outer rail when running around sharp curves.

,The invention consists of novel features and arts and combinations ofthe same, as will e more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanyingdrawings, forming a part of this s ecification, in whichsimilar characters of re erence indicate corresponding parts in all theviews.

Figure 1. is a side elevation of the improvement as applied to acar-axle. Fig. 2 is an enlarged sectional plan view of the same, andFig. 3 is a cross-section of the same.

Onthe journal A of a car-axle A, carrying a car-wheel B, is looselyfitted a sleeve 0, mounted to turn with and to slide length-- purposeprovided with a longitu rial groove or ireyway into which fits a key I),secured to the sleeve C. The sleeve O is provided with spaced annularracewa s O and C containing sets of balls E and respectively, engaged attheiriouter points by the innerwalls or facesof cups F and F, screwinglengthwise in a journal box or casing Gr, mounted to slide up and downin the usual manner in the bearings of the truck.

The bottom walls of the annular races C and O are inclined approximatelyparallel to the corresponding faces of the cups F and F, and the racesare sufficiently broad to allow sidewise play of the balls to preventjamming or crowding of the balls. g

The sleeveO is pressed on at its inner end by one end of a spring I,coiled on the axle and, abutting against ub of 'the 'car-wheel B, so asto exert an outward pressure against the sleeve C, and hence when thecar is rounding a sharp curve the friction of the car- 'wheel flangesagainst the outer rail is lessened to a considerable degree, as thesprin I allows the sleeve C to yieldthat is, to s ift its positionlengthwise Within the box or casin G.

In order to retain the sets of balls E an E in their races C and C,retaining-rings J and J areprovided, screwing on the corresponding endsof the sleeve'C and held in position by jam-nuts Kand K, likewisescrewing on the said sleeve;

The outermost cup F is closed, as plainly indicated in Fig. 2', whilethe innermost 0111 F is provided with a central aperture for the passageof the inner end of the sleeve C, and on this inner cup Fe is held adust-ring L,ma de of leather, rubber, or other suitable material,fitting with. its innerwall the eri heral face 'of the sleeve 0, soas-to'ren er t e bearing dust -proof and oil ietaining. The dust ring Lis held in pl-ace by a metallic washer N, {itting against the end of thecup F and held in place .iy a ringshaped nut O, screwing in the innerend of the box G. By this arran ement the cup F issecured in place aftert e cup is adjusted, and a similar washer N and nut O engage the cup Fto hold the latter in position after the cup is screwed into the desiredosition within the box or casing G.

if esired, additional fastening devices for the cups F and F may beemployed for instance, as shown in the drawings, two screwrods P and i?may be used, each extending through lugs G and G formed or secureexteriorly on the box or casin G, so that when the nuts of thescrew-rods 1% P are screwed up "the box tends to clamp the cups F and Fin place to prevent accidental movement thereof within the box or casingG.

It is understood that the box or casing is 1. A ball-bearing, com risinalongitudinally-grooved journal, a s eeve aving a key fitting in thegroove of the journal and rovided with spaced annular raceways, ha} 5 ineach of the raceways, a spring pressing the sleeve'in the direction ofits length, a box, a

cup screwing intoeach end of the box and secured to the outer end of theinner cup I rm and fitting the peripheral face of the sleeve.

2. A ball-bearing, comprising a-journal, a spring-pressed sleeve havingsliding and guided movement on the journal, said sleeve eing providedwith spaced annular raceways, allsin the raceways, a box, a cup securedin each end of thebox' and engaging the balls, the outer cup beingclosed and the inner one having an opening to receive the sleeve, meansfor locking the cups in position,

and a dust-ring secured to the inner cup and fitting upon the sleeve.

J) 3. Aball-bearing, comprising a box, 'a journal, a sliding and sprinjournal, said sleeve spaced annular raceways, ways, and cups secured'inthe ends of the box and engaging the balls. 4. In a ball-bearing, asliding and spring-pressed sleeve on the journal, said sleeve havingspaced raceways, each formed by an annular groove and a ring se- 1-pressed sleeve on the eing) rovided with a ls in the race-.

box, a journal, a

balls in the raceways, and a cup secured in each end of the boxand enaging the balls.

5. In a ball-bearing, a ox, a journal, a I sliding and spring-pressedsleeve on the journal, said sleeve bein provided with spaced annularraceways, balls in the raceways, cups secured in the ends of the box andengaging the balls, a dust-ring fitting upon the inner end of thesleeve, a Washer engaging the dust ring and end of the inner cup, and aring-nut screwin into the box into engagement with the Was ier.

6. In a ball-bearing, a box, a journal, a spring-pressed sleeve havingsliding and guided movement on the j'ournal, said sleeve 'eing rovidedwith spabed annular race- Ways, alls in the raceways, cups screwing finto the ends of the box and engaging the balls, and means for lockingthe on s in position after they have been adjusted? In testimony whereofI have signed my name to this specification in the presence of 1 twosubscribing witnesses.
